PhytoSERM to Prevent Menopause Associated Decline in Brain Metabolism and Cognition

• Status: Not yet recruiting
• Trial end date: 2028-02-28
• Target enrollment: 0
• Participant gender: All

Summary

This is a proof-of-concept phase 2 clinical trial to investigate the safety and effect of the phytoestrogenic supplement PhytoSERM on regional brain metabolism by fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG-PET) in peri- and postmenopausal women. The investigators hypothesize that there will be a significant difference between the PhytoSERM group and placebo group in glucose brain metabolism.
